More than four (4) unexcused absences may result in the student being dropped from the course. Acceptable excuses are normally limited to illness, military duty, and representing the College in an official capacity. The instructor may require written documentation in order for the absence to be regarded as excused. Excessive tardiness or leaving early may be counted as an additional absence when, in the instructor’s estimation, the student has missed the equivalent of one class. Students should keep all course-related material (notes taken in class, handouts, assignments, etc.) in a notebook that is taken to each class meeting. The course textbook and a scientific calculator should also be brought to every class. Quizzes will be given from time to time during the semester. There is not a pre-set number of quizzes to be given. These quizzes can occur at any time during the class meeting period and do not have to be announced beforehand. Absence, tardiness, or leaving early may cause you to miss a quiz. Missed quizzes can not be made up unless (1) you have already depleted your drop privilege for quizzes and (2) you have an acceptable excuse for missing the quiz. Acceptable excuses are normally limited to illness, military duty, and representing the College in an official capacity. The instructor may require written documentation in order for the absence to be regarded as excused.

COURSE COMPETENCIES Upon completion of the course, the successful student will be able to: Explain the general process that scientists use to investigate natural phenomena. Convert a measurement expressed in one unit to some other unit, given the appropriate conversion factors. Use density as a special kind of conversion factor to relate mass and volume Properly apply significant figure rules when making measurements or dealing with measurements reported by others. Properly apply significant figure rules when performing calculations based on measured data. Explain / Identify general features of the periodic table. Identify commonly encountered compounds as being either ionic or covalent. Predict the chemical names and chemical formulas of binary compounds. Given a chemical name, arrive at the corresponding chemical formula, and given a chemical formula, arrive at the corresponding chemical name. Identify chemical reactions by class – that is, specify whether a chemical reaction is a combination, combustion, decomposition, displacement, or metathesis reaction. Balance chemical equations belonging to any of the above reaction classes. Understand the concepts of oxidation and reduction, assign oxidation numbers to elements in compounds, tell whether or not a chemical reaction is a redox reaction, and if it is, balance the redox reaction.

Apply solubility rules to write complete formula, ionic, and net ionic equations for displacement and metathesis reactions. Apply solubility rules and the characteristics of strong and weak acids and bases to write complete formula, ionic, and net ionic equations for acid-base neutralization reactions. Apply the concept of stoichiometry to calculate the percent by mass of each element in a chemical compound of known formula. Apply the concept of stoichiometry to calculate the empirical formula of a compound if given either the mass percentages of the elements in the compound, or the actual masses of the elements present in a sample of the compound. Apply the concept of stoichiometry to calculate the molecular formula of a compound if given the molecular weight of the compound and also given either the mass percentages of the elements in the compound, or the actual masses of the elements present in a sample of the compound. Apply the concept of stoichiometry to chemical reactions, to calculate the mass of a product that can be obtained from given masses of reactants, and calculate the mass of a particular reactant needed to prepare a desired mass of product, in both cases taking into account the percentage yield of the reaction. Understand and explain the behavior of gases, and the relationships between the properties of pressure, volume, temperature, and number of moles of gas. Utilize Boyle’s Law, Charles’ Law, Gay-Lussac’s Law, the combined gas law, and the ideal gas law to carry out gas calculations of chemical interest. Apply Graham’s Law of Effusion to calculate gas effusion times, and to calculate the molecular weight of an unknown gas. Apply the concept of stoichiometry to chemical reactions in which a reactant or product is a gas (that is, combine stoichiometric calculations and gas calculations). Understand what is meant when a chemical reaction is said to be endothermic or exothermic; know the effect of such reactions on the temperature inside an isolated system, and the effect on the temperature of the immediate surroundings when the system is not isolated. Understand what is meant by heat capacity and specific heat capacity and use these concepts to relate heat gain or loss to temperature change. Understand the technique known as calorimetry, and use calorimetric data to calculate the enthalpy change of a chemical reaction. Understand what a state function is, and use this concept and Hess’ Law to calculate the enthalpy change for a reaction which can not actually be carried out using the enthalpy changes for appropriate other reactions which can be carried out. Use the “products minus reactants” formula to quickly calculate the enthalpy change for a chemical reaction. Calculate the enthalpy of formation of a substance in a chemical reaction given the enthalpy change of the reaction, and the enthalpies of formation of the other substances in the reaction. Explain how the shell model of the atom accounts for the line spectra of elements. Understand the relationship between frequency, wavelength and photon energy for electromagnetic radiation, and calculate any two of these quantities given the third one. Use the known energy levels of shells in the hydrogen atom to calculate the line spectra of hydrogen. Relate the position of the elements in the periodic table to the electronic structure of their atoms. Write electron configurations and draw orbital diagrams for atoms based on their position in the periodic table. Specify the four (4) quantum numbers (n, l, ml and ms) for electrons in atoms. Understand the relationships between the four (4) quantum numbers, and the rules governing which values are allowed and which values are not allowed for these quantum numbers. Explain the Heisenberg Uncertainty Principle, the Pauli Exclusion Principle, and Hund’s Rule. Explain why atomic properties vary in a regular was as one compares elements along a row or down a column of the periodic table. Arrange elements in order of increasing (or decreasing) values of selected properties, such as electronegativity, atomic radius, ionization energy, etc, based on their locations in the periodic table. Predict and draw the most probable Lewis structure for common molecules and ions. Assign VSEPR formulas for molecules and ions based on their proposed Lewis structures, and use these to predict molecular geometry and whether the molecule (or ion) should be polar or non-polar.
